Now that cpusets have been in the mainline kernel for
some time you should be able to do this with any modern

I contemplated doing this on our Barcelona cluster, but
sacrificing 1 core in 8 was a bit too much of a high price
to pay. But people with higher core counts per node might
find it attractive.
